Hybrid Tea rose plant named `Selantimoon`

ABSTRACT

A new rose variety of the Hybrid Tea class, characterized by its continuous production of large pink flowers, borne singly on upright stems on a bush of medium height, having glossy foliage and a mild honey-like fragrance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class, which was originated by me by crossing the variety `Jacaranda` with an unnamed seedling (SR 80.077).

The primary objective of this breeding was to obtain a new large type rose with a good presentation and bud shape in different colors. Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which I am aware are:

(1) A large typically pink flower;

(2) Rapid flowering cycles;

(3) Highly glossy foliage;

(4) A vigorous upright plant of medium height; and

(5) A plant which has very few prickles on the rachis.

Asexual reproduction of the new rose variety by cutting and grafting using Nathal Briar as rootstock, as performed in a greenhouse in De Kwakel, The Netherlands, shows that the aforementioned characteristics and distincions come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The new variety of rose plant is illustrated by the accompanying photographic illustrations, of which:

Sheet 1 shows a full face view of the flower; and

Sheet 2 shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it reasonably possible to make the same illustration of this character.

The following is a detailed description of this new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart e.g. "55C" is plate "55C" of The Royal Horticultural Society Colour Chart.
